Cam,
Here's pretty much the main thing I'd like to discuss:
I think the best comparison for Coley is Clemson Wide Receiver Sammy Watkins. Their games compare favorably, with Watkins being the faster player of the two. While I do not think that Coley will match Watkins’ Freshman Season statistics (National Freshman of the year, 1st team All-American, 82 catches, 1219 yards, 12 TDs, 231 yards rushing [reverses], and nearly 1,000 return yards and 2 return touchdowns), they are within the reach for a player of Coley’s caliber.
From what I've seen, I'd immediately disagree with this comparison. After re-reading your post, it seems like you mean more in terms of impact? Still, you say their games "compare favorably," which I don't really see. Sammy's main weapon is otherworldly acceleration. I think Coley is fantastic in and out of his breaks. He sinks his hips easily and pops out of his cuts, but it's not on the level of Sammy. I don't know if it's because he hasn't hit the weight room sufficiently. Nevertheless, I think Coley's a different kind of WR than what we see from Watkins: who can take a beating *out of the backfield* as well as he can do his damage outside of the hashes.
On another note, one thing I really found insightful from your post was that Coley had added routes to his game. Personally, that was what scared me the most from Amari Cooper last year. While many had him as the top player in the state, I thought he was closer to "Top 6" because I rarely saw versatility in his routes. In short, he ran 9 routes and post patterns. I guess it didn't really matter because that's where he did serious damage as a true Frosh. I'm glad to hear Coley is adding elements to his route running, because he'll run more digs here than he will post patterns.
